rebuilding my 11 yr old shower

[v1rtu0s1ty]

What if, unexpectedly, when you laid the tile in wall, 1 whole piece of tile covered the shower? Is there any porcelain rounded bit like 3 inch in diameter?

[Dave Taylor]

That's so unexpected... I'm not sure what you mean. Hole saws up to (1 3/4") diameter are available in the TYW on-line store.

Yup.
Sounds like "plumber burn" to me also.

Nothing at all to worry about, it happened when it was sweat.

Yep, my question was so confusing but you got the answer correct! Ahhh, porcelain bits are really expensive.

Depending upon your particular situation which I don't quite understand, could you use one of the methods covered in this Liberry Thread on cutting hole in tiles? go here

Sorry if I was so confusing. I'll just make sure that when I lay the tiles, the tile that will line up to the hole will fall in a corner. This way, cutting a circle is easier. I'll plan ahead with the tile layout. Thanks guys!

I'm going with wonderboard for my wall in the shower. I still have thin set left when I built my laundry tiles. Is it ok to use that same thinset for the shower wall tile and the wonderboard from home depot? If I remember correctly, it's the thinset that dries quickly, traffic in 6 hours from what they claim

[Madison Mike]

Welcome - as long as the thinset isn't old you should be fine. I generally won't use a partial bag if I don't know for sure that it's less than a month since I opened it. If you have an unopened bag left over from your last project you should be OK as long as it's not more than about 9 months old. They say shelf life is a year on mortar, but that year starts the second it gets filled into the sack at the factory.

Just a side note: if you have mortar that says it's ok to walk on the install after 6 hours it must be a rapid setting mortar. It's a fine quality mortar, just trickier to use because it sets up so fast, but you must know that since you used it when you set your laundry tile, right??

Yep, bag is opened and less than a month. I should be fine then. But found out a while ago that I only have few left. I need to buy a new one then

Thanks for the aging tips. I didn't know that!

Hey guys,

I removed some few tiles again. Behind the tiles was a cement board. I used chisel to knock off the tiles. I attached 2 pictures so you can see the condition of the cement board. The second picture is a closer shot. Currently, it is showing the little square mesh. Can I still use this cement board or should I put a new one?

[Shaughnn]

Virtue,
It looks like the fibrglass reinforcement mesh has delaminated from the cement board? If that's the case, then it's no longer being a "reinforcement" and instead it's become a kind of "inhibitor" between your tile and a proper bond to the cement board. If much of the cement board looks like the bottom picture, I'd say it needs to be replaced. Sorry for the bad news.

Thanks. It's good though that I can't use it anymore. Or else, I could have wasted the tiles that I will be sticking to it. Thanks again!

Mastic, no tape on the seams, poor bond, inadequate coverage. No wonder you are ripping it out.

How long did it last?

I don't know if I understood you Mike. But bathroom is same age as the house which is 11 years old.

Anyways, assuming I've got an area where I need to put 2 cement boards side by side(just like the first picture), do I need to tape them? Which tape should I buy at Lowe's or Home Depot?
